Product Description:
The KDA 2.1-150-3-AY0-W1 is manufactured by Bosch Rexroth Indramat and belongs to the KDA Spindle Drives series. The product is in series 2 and serves as the regulated power stage between a machine-tool CNC controller and a high-speed motorized spindle during precision machining. The module converts a constant DC bus into variable three-phase output and supplies the torque and speed control needed for metal-cutting, grinding, or boring operations in automated production lines, where stable spindle response supports accurate surface finish and repeatable process timing.
The drive is a spindle drive and can deliver a continuous output of 150 A while drawing energy from a 300 VDC bus link. Thermal energy is removed through a mounted heat sink blower. That blower receives its own single-phase supply of 220 V, 50/60 Hz, so main power wiring and cooling power are separated. Speed reference signals arrive as an analog command, allowing the CNC to vary spindle speed smoothly across the operating range. The unit has no additional interface option and supports the standard spindle enable, fault, and ready terminals used in machining centers. These standard terminals support basic machine control without a separate fieldbus card.
System reliability is supported by forced cooling, which helps maintain stable internal temperatures during sustained spindle loading when ambient air is between 5 to 45 °C. Installation is permitted up to 1000 m above sea level without output derating. Feedback flexibility is expanded by a second encoder input and a synchronous input, so the drive can process both spindle-mounted encoders and an external master clock for orienting, phase matching, or C-axis positioning. This supports coordinated spindle functions in machines that require orientation before tool changes.
